Indices

Corruption Perceptions Index (CPI): The CPI ranks countries/territories based on how corrupt a country’s public sector is perceived to be. It is a composite index, a combination of polls, drawing on corruption-related data from expert and business surveys carried out by a variety of independent and reputable institutions. The CPI reflects views from around the world, including those of experts living and working in the countries/territories evaluated. For a country/territory to be included in the ranking, it must be included in a minimum of three of the CPI’s source surveys. Thus, inclusion in the index is not an indication of the existence of corruption but rather dependent solely on the availability of information.

Bribe Payers Index (BPI): a ranking of leading, exporting countries according to the perceived likelihood of their firms to bribe abroad. It is based on a survey of executives focusing on the business practices of foreign firms in their country.
